To all whom it may concern:

such manner a's to allow for a proper distri- Be 'it known'that I,UzzIEL P. SMITH, .a' bution of the supporting and driving strains,

citizen of the UnitedStates, residing at Akand it will be-noted that inthe present inron, in the county of Summitand State of Ohio, haveinvented a certain new and useful Improvement ,in Vehicle-Wheels, ofwhich scri tion. e object of the present invention s to provide avehicle wheel which shall have a the following is a full, clear,-andexact decushion of any suitable form or type interposed between thehubsection.

and the rim or spoke The general type of wheel one well known in theart, being designed to hold the cushion, which may be composed either ofsprings or a neumatic tube, nearthe center of the whee in order that itmay be free from the wear and placed outside of the rim. One of thegreat difliculties found in connection with such wheels is the provisionof a rotary driving connection between the hub and the spoke sectionwhich shall permit of a relative oscillation between the two in alldirections in the vertical plane of the to permit a transmission oftorsional strain to the cushion. The structure which I have devised isdesigned to overcome the diflicul- 3o ties above set forth, and toattain all of the advantages which should accompany this particular typeof wheel.

- ,Referring-to the accompanying drawings,

which form a part of this application, Figure 1 is a transverse verticalsection of an embodiment of my invention in which a. cushion consists ofspiral s rings. Fig; 2 is a section taken at right ang es to Fig. 1along the line 22. Fig. 3 is a section at right 'anglesto 40 Fig. 1taken along the line 3-3, broken away in part to show the location ofone oft'he driving disks.

The hub section A of the wheel is mounted upon and secured to thedriving shaft A in any'suitablemanner and has seats A there- 'about forthe cushioning devices, which, in the present instance, are as abovenoted, composed of spiral compression springs B.

It isobvious that these springs might be replaced by pneumatic balls ora tube or equiv-.

.alent devices.

- Projecting from the hub in a radial plane is a-web A having (pockets.A therein in which are snugly fitte disks '0 capable of rotativemovement in the pockets. These pockets are. distributed around the webin tear to which it is subject when,

wheel and be such as not pockets are a ainst re side of the web, this isdeemed preferable.

The rim or spoke section D has a ring surrounding the hub adapted toinclose the cushioning devices, the central such lay as the cushioningdevices are designed to take care of.

Projecting internally from and rigid with the spoke ring is a web Ddesigned to lie adjacent to'the web rojecting from the hub. In thissecond we also I have provided pockets D for receiving disks 0 whichlocated so as to mate with the ockets A in the web projecting from thehub. Each. pair of mated disks is with an eccentric connection in theorm of a stub or pin C Owing to the fact that the connection between theseveral C is eccentric and each disk tate about its own axis, it isrovided pairs of disksmay be all located on one 1f for reasons ofconstruction opening of the ring being of sufiicient diameter to permitrelative movement'between the hub and the spokering. may take place inall directions in the vertical plane of the wheel. For the purpose ofpermitting this. relative movement, it is of course necessary that therebe a space outside of the erimeter of the web projecting from the hubsufficient to allow of the relative movement the event that this webproximately central shown in Fig. 1, it wi is located in the aplpositionin which it is by making an annular recess D in t ring D.

For the e spoke urpdse of holding the spoke ring ative sidewise end aong the shaft, I provide the hub with guiding and retaining rings orplates 5 which may be secured in any way desired;

of the parts, and in of course be necessary .to provide the space forthe proper play movement From the structure above described, it is lainthat the relative vibration betweenthe ub and the spoke ringv in theplane of the a wheel is not interfered with by the'driv' disks, beingcontrolled as to its extent by the cushioning devices interposed betweenthe two sections. The rotative movement of the hub section istransmitted to the s oke section by means of the mated pairs of iskswhich are each free to rotate in their respective pockets and aretherefore capable of transmitting motion without in any manner affectingthe vibratory motion in the radial direction. In this respect theyconstitute a connection different from any heretofore known, which ispositive in its character, being devoid of looseness of play or anyother feature which might produce shock or cause the rotative motiontobe transmitted through the cushionin device.'

Having thus descri ed my invention, I claim:

1. A wheel com rising a hub section and a rim section, a cus ion betweensaid sections adapted to receive the shock of relative movement betweenthe two, a driving connection between said hub section and rim sectioncomprising a disk revolubly mounted on a hub section and eccentricallyconnected-with a disk revolubly mounted on the rim section.

2. A wheel com rising a hub section and a rim section, a cus ion-betweensaid sections adapted to receive the shock of relative movement betweenthe two, a driving connection between said hub section and rim sectioncomprising a revoluble disk carried by the hub section and eccentricallconnected with a revoluble disk carried y the rim section, said disksbeing so mounted that the individual axis of rotation of each diskremains fixed relatively to ,the section by which the disk is carried.

. 3. A wheel comprising a hub section and a rim section, cushioningmeans between said sections, each section rovided with pockets and disksrevolubly tted in said pockets, said pockets and disks being so locatedthat when the wheel is assembled, the disks in the one section may bebrought face to face with the disksin the other section, the disks ofone section being each pivotally connected with a disk of the othersection at a point eccentric to each disk.

In testimony whereof, I hereunto afiix my signature -in the presence oftwo witnesses.
